Apple's fourth-gen iPod Nano has surfaced on the web, well ahead of next week's anticipated announcement of the product.

Online business-oriented market, Alibaba, lists a screen-protector product for the new music player:

Apple's 4G iPod Nano

It's worth noting the device alleged to the 4G Nano matches pics that appeared around the web a week or so back, so it's a sure as mustard this is the what the new version of the player will look like.

It also matches the look of new iPod cases spotted at last week's IFA consumer electronics show in Berlin.

Alibaba also refers to a similar accessory for the "iPod Touch 2", though the photo used appears identical to the first-generation Touch.
